Ooh, ooh! I'm indian (by ethnicity, not nationality) and we have an entire shelf or two devoted to indian books, because my mother reads them a lot. I read A Suitable Boy when I was 15 and it was great, but I haven't read it since (maybe I should, I think the politics went a bit over my head a the time). It certainly wasn't the first I've read, and there are a lot we own that I still haven't read, including The White Tiger, The Glass Palace, Brick Lane (does that count?), Six Suspects...etc etc.
A few I really like are The Inscrutable Americans (really funny - I recommend if you want some comedy!), God of Small Things, Family Matters....
